Broken Anchors in Widget

Xenu backlink checker reports there are 3 anchors on every page in the blog (where WP Mash Social Widget appears) that are broken or not found, here is the result of the 3 tags being reported:

domainname/blog/#viewed not found
domainname/blog/#recent not found
domainname/blog/#tags not found

How can we fix this issue?
